Esempio di codice

Go

Prima di provare questo esempio, segui le istruzioni di configurazione di Go disponibili nella guida rapida di Compute Engine sull'utilizzo delle librerie client. Per ulteriori informazioni, consulta la documentazione di riferimento dell'API Go di Compute Engine.

Per eseguire l'autenticazione in Compute Engine, configura Credenziali predefinite dell'applicazione. Per maggiori informazioni, consulta Configurare l'autenticazione per un ambiente di sviluppo locale.
